Solutions for Chapter 14: Nuclear Magnetic Resonance Spectroscopy

Compounds containing multiple aromatic rings fused together.

The conjugate base of acetylene or any terminal alkyne.

A structure that bears a positive charge.

An acid and its conjugate base or a base and its conjugate acid. (15.1)

A reaction involving the loss of a leaving group and formation of a p bond.

For cyclohexane, the steric interactions that occur between the flagpole hydrogen atoms in a boat conformation.

The modern NMR method that is based on a constant magnetic fi eld, a short pulse of electromagnetic radiation, and a mathematical Fourier transform to produce the spectrum

CFCs that were heavily used for a wide variety of commercial applications, including as refrigerants, as propellants, in the production of foam insulation, as fire-fighting materials, and many other useful applications.

When orbitals of equal energy are available but there are not enough electrons to fi ll all of them completely, one electron is put in each before a second electron is added to any

A constant characteristic of a particular solvent that gives the decrease in freezing point as a function of solution molality: ?Tf = -Kf m. (Section 13.5)

A two-step process for the Markovnikov addition of water across an alkene. With this process, carbocation rearrangements do not occur.

A voltaic cell that cannot be recharged. (Section 20.7)

A process that can go back and forth between states along exactly the same path; a system at equilibrium is reversible if equilibrium can be shifted by an infinitesimal modification of a variable such as temperature. (Section 19.1)

A compound that contains no p bonds.

A region of space around a nucleus that can be occupied by electrons, corresponding to a principal quantum number

A sodium or potassium salt of a fatty acid

The observed rotation of the plane of polarized light when a sample is placed in a tube 1.0 dm in length and at a concentration of 1 g/mL for a solution. For a pure liquid, concentration is expressed in g/mL (density).

An organohalide in which the alpha (a) position is connected to three alkyl groups.

A reaction that has a rate equation in which the sum of all exponents is three

A model of bonding that places electron pairs between adjacent atoms to create bonds.
